The book takes you on a tour of the essential technologies and modern defenses at your disposal to help you maintain network uptime and data integrity. Part I covers the basics, introducing terms and concepts and laying the foundation of a solid security structure. Part II examines 2 components of security-cryptography & security policies. Part III looks at the various security components. Separate chapters cover web security, router security, firewalls, intrusion detection systems (IDS), remote access security, virtual private networks (VPN), Public Key Infrastructure (PKI), wireless security, and logging and auditing. Each chapter in this section is a self-contained tutorial, allowing you to skip to those topics of greatest interest or primary concern. Part IV includes several reference appendixes, including the Cisco SAFE Blueprint, NSA guidelines, and SANS policies. | |
